508.8 -II. Evaluation scheme for visible effects
| AMOUNT OF GROWTH | RATING | COMMENTS |
|---|---|---|
| None | 0 | Substrate is devoid of microbial growth. |
| Trace | 1 | Scattered, sparse or very restricted microbial growth. |
| Light | 2 | Intermittent infestations or loosely spread microbial colonies on substrate surface. Includes continuous filamentous growth extending over the entire surface, but underlying surfaces are still visible. |
| Medium | 3 | Substantial amount of microbial growth. Substrate may exhibit visible structural change. |
| Heavy | 4 | Massive microbial growth. |
